The circumference is given by
C= pi *d
Substitute in what we know
62.8 = 3.14*d

20 =d
Answer:
B
Step-by-step explanation:
So for the first square we Have ab*a
When you multiply variables then you add up their powers so b^1a^1+a^1= (a^2)(b^1)
Second box is -3 * a which is equal to -3a
third box is 2b * ab = 2ab^2
fourth box is -3 *2b = -6b
Answer:
A = 1
